I have a 9.0-PRERELEASE system:
Running on a pair of SSDs in zfs root mirror:
That indicates disk activity at about 1 second intervals that I have traced to hald. When I kill hald, activity stops.
I'm wondering if hald activity writes to disk causing wear on SSDs and what I might do to prevent it if so?
Code:
tsunami# uname -a
FreeBSD tsunami.lan 9.0-PRERELEASE FreeBSD 9.0-PRERELEASE #0: Fri Dec 2 07:25:19 PST 2011 root@tsunami.lan:/usr/obj/usr/src/sys/TSUNAMI amd64
Code:
